Hi.
I'm using jasper reports for the first time and my objective is to integrate
it into my web application where i'm using spring, struts2 and hibernate.
For start i create a simple and example with 2 classes: User and Morada
where Morada is a List.
Soo, as far i understand i need to create a report and then a subreport to
represent this List...
The problem is that i get all the User information except this List of
Morada.... My subreport stays blank.....
Here´s my code:
User.java
public class User implements Serializable {
private static final long serialVersionUID = -270523345211099505L;
private int id;
private int version;
private String nome;
private Date dataNascimento;
private List<Morada> moradas = new ArrayList<Morada>();
private String carro;
public User() {
super();
// TODO Auto-generated constructor stub
}
public User(int id, int version, String nome, Date dataNascimento,
List<Morada> moradas, String carro) {
super();
this.id = id;
this.version = version;
this.nome = nome;
this.dataNascimento = dataNascimento;
this.moradas = moradas;
this.carro = carro;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getVersion() {
return version;
}
public void setVersion(int version) {
this.version = version;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public Date getDataNascimento() {
return dataNascimento;
}
public void setDataNascimento(Date dataNascimento) {
this.dataNascimento = dataNascimento;
}
public List<Morada> getMoradas() {
return moradas;
}
public void setMoradas(List<Morada> moradas) {
this.moradas = moradas;
}
public String getCarro() {
return carro;
}
public void setCarro(String carro) {
this.carro = carro;
}
}

private int user_id;
private String rua;
private String cidade;
private String cod_postal;
public Morada() {
super();
}
public Morada(int id, int version, int user_id, String rua, String
cidade,
String cod_postal) {

this.id = id;
this.version = version;
